TL;DR: OpenTelemetry GenAI conventions intentionally record agent type, not instance identity, which creates an attribution ceiling that can hide prompt injection in autonomous agent fleets unless runtime topology and observability are aligned, according to ARMO. For autonomous systems, the broken assumption is that behavior can be attributed to a stable, reviewable agent instance after execution begins.
NHIMG editorial — based on content published by ARMO: Prompt Injection Telemetry for Autonomous Agents: The Attribution Ceiling Decides What You Detect
By the numbers:
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, inappropriately sharing sensitive data, and revealing access credentials.
Questions worth separating out
Q: How should security teams test whether prompt injection telemetry can name the compromised agent?
A: Deploy two agents from the same definition in the real runtime topology, give one normal behaviour and one intentionally abnormal behaviour, then see whether the alert resolves to a specific agent instance.
Q: Why do autonomous agents make behavioural detection harder than traditional workloads?
A: Because the key security question is no longer whether a request was authorised, but which agent instance performed the action and whether that instance behaved differently from its own baseline.
Q: What do teams get wrong about agent traces and prompt injection detection?
A: They assume a trace proves actor identity, but traces usually prove only that a set of spans belonged to one run.
Practitioner guidance
- Measure your attribution ceiling before buying detection tooling Run two agents from the same definition in the exact topology you ship, give one normal work and one anomalous work, then inspect what the alert names.
- Separate debugging telemetry from security evidence Treat gen_ai.agent.id and trace identifiers as useful triage signals, but require kernel, cloud audit, or identity-plane evidence for containment decisions.
- Unpack the highest-risk agent classes Give regulated, write-capable, or externally connected agents their own process, pod, and credential boundary.
What's in the full article
ARMO's full blog post covers the operational detail this post intentionally leaves for the source:
- A worked explanation of how the OpenTelemetry GenAI conventions shape agent identity fields and cardinality decisions.
- A practical two-agent test that shows how to measure your attribution ceiling in the runtime you actually ship.
- Examples of how kernel, process, pod, and service-account boundaries affect whether a signal can name one agent instance.
- Discussion of how framework-level context propagation can be used for triage while evidence still requires stronger identity sources.

Autonomous agent telemetry creates an attribution ceiling that many security teams mistake for visibility. The data may be complete, but the identity resolution is not. If one agent definition is mapped to many runtime instances, then prompt injection detection becomes an exercise in workload inference rather than actor attribution. Practitioners need to stop assuming that a logged event can also name the compromised agent.
A few things that frame the scale:
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, inappropriately sharing sensitive data, and revealing access credentials, according to AI Agents: The New Attack Surface report.
- Only 52% of companies can track and audit the data their AI agents access, according to AI Agents: The New Attack Surface report.
A question worth separating out:
Q: Who is accountable when agent telemetry cannot distinguish one instance from another?
A: Accountability sits with the team that chose the runtime topology, because packing multiple agents into shared pods, processes, or worker pools sets the attribution ceiling before any detection tool is deployed. Standards can guide telemetry shape, but they do not remove the governance duty to ensure the actor can still be named.
